Drill with Parquet files on Azure Blob Storage

[Roberto Grandi]

Dear Drill Users,

I am using a parquet file folder on Azue Bob Storage with this structure

/root
  /site=site1
    /datekey=20160501
      /file-1-.parquet
      /file-2-.parquet
..
    /datekey=20160502

When I Run queries on this form

SELECT site, datekey, other columns FROM root

I always obtain NULL values for my partition keys, hostname and datekey.

Did anyone experiment this behavior on Azure Blob Storage?

Many thanks in advance dor all the help you can provide.

BR
Roberto
